Title: Production of metal pipe lined with synthetic resin
Inventor: OGAWARA HIROSHI
IPC: B29C63/34
Filed: 1978-03-30
Abstract: PURPOSE: Synthetic resin tubes of small diameter are inserted into a continuous metal pipe of large diameter with specific intervals and bonded to the metal pipe, thereby producing metal pipes lined with synthetic resin with uniform thickness of adhesive layer.  
     CONSTITUTION: The inner surface of metal pipe with a length of over 1 m and a diameter of over 50mm or the outer surface of synthetic resin tubes with small diameter that are to be inserted into the metal pipe is coated with an adhesive of foaming resin so that the resin layer occupies 10W90% of the gap space between the metal pipe and the resin tubes. The synthetic tubes are arranged so that the average interval between the metal pipe and the synthetic resin tubes may be 0.2W2mm before foaming and then they are heated so that the inner surface of the metal pipe reaches 80W100°C to foam the adhesive and simultaneously harden the resin, thereby fixdng the resin tubes to the metal pipe.

     CONSTITUTION: A third magnet 10 is disposed in the rotating direction of a donor drum 2 of a gar A. The third magnet 10 is so disposed that the poles of the mutually opposing first magnet 3 and the second magnet 5 in a sleeve 4 become different  from the pole of the first magnet 3 and become the same as the pole of the second  magnet 5. Hence, two magnetic fields 7, 70 are formed among the abovementioned  three magnets. When toner is sent in such magnetic fields along with turning of the sleeve 4, the toner arrays along the magnetic lines of force forming the respective magnetic fields. Even if a large volume of the toner is scooped up by the sleeve, it is held between the magnetic fields 7 and 70 and when it is small, the toner existing in the magnetic field 70 moves to the towers or insufficient heights thus maintainig the heights of the towers constant.

Title: Data recording device for vehicle
Inventor: SHINDO MASAHIRO
IPC: G01D9/00
Filed: 1994-03-09
Abstract: PURPOSE:To clearly record details that a vehicle becomes an urgent state. CONSTITUTION:When a shock by which the vehicle is judged to become the urgent state is detected (step 110), the priority of data recorded in a preservation memory is compared with that of data in a buffer (steps 112 and 114). When data of the buffer is taken precedence over, data in the preservation memory is rewritten into a recording memory (step 116), and data of the buffer is written into the preservation memory (step 118). When the priority of data in the preservation memory is high, the priority of data in the recording memory is compared with that of data in the buffer (step 124). Data of high priority is recorded in the recording memory (step 122), and an operation is stopped when the recording of data is judged to stop so as to protect recorded data (steps 126 and 128).
